Design cheaper IMU board #2

Open ras-marques opened 9 months ago

ras-marques commented 9 months ago

While not knowing exactly what IMUs to use, the BMI270 together with a magnetometer is a good option. The goal is for the board to fit the fingernail. 4 Layer boards and components on both sides are a must for this to work.

Both the BMI270 and BMI160 are good options. They are also not too big and use the same pinout so for a custom PCB with a magnetometer you only need a single board design because both chips can be used. If budget is a problem and you don't mind having to recalibrate them more often then you don't need the magnetometer.

I still have to try some recalibration routines to see if I can dismiss the use of the magnetometer. I have some things in mind, but they are tied to what other glove hardware can do, will update when I have news about that.

ICM-20948 based board has been designed, will close after confirming it is working.
